OK I now have both cards installed and crossfired successfully, I also have three monitors plugged in, on the top I have one in HDMI, one in DP, In the bottom one I have in in DVI. Why aren't all three monitors working?

okay I have all three working but I want to add a fourth and fifth screen how does one achieve this if I am only able to use the three ports on the main card?
 
It depends on the ports on your video card and the ports on your monitor(s). There are too many possible combinations to list.

You could use a dual-link DVI cable which has 2 digital outputs, or an analog and digital out. You may need a DVI-->HDMI adapter for one of your monitors. You might need an active displayport adapter which allows a 'daisy-chain' of monitors if your video card supports it -- but that requires a displayport-out port on the monitor.

If one of the ports is d-sub, it would output to a single analog monitor.

If Windows does not recognize your configuration, you have to enter CCC, extend your Desktop to the display(s) and set your grouping. Be sure to save the profile.

Ok so I has four monitors working just fine, until I rebuilt my monitor stand I plugged everything back in and fired my pc up. It kept reseting itself whilst windows was loading so I went down to 1 monitor. That worked fine separately added upto 3 they work fine. Now when I plug the fourth in the pc crashes and resets if it is already logged on and then crashes upon attempting to load windows. Alternatively if I have four plugged in before turning it on it crashes upon loading windows. I do not understand what the problem is does anyone else know or have a remedy for this please as I am totally confused as to why it worked and now doesn't. Other than what the monitors sit on nothing has changed same cables same ports on the graphics card?!?!?!?!
